The comment is within a very large document and you conveniently missed out the bold type above
On the basis of evidence available to us we cannot conclude that
overdiagnosis is occurring at scale, particularly given the gaps in
population prevalence data and data reporting
Or that he goes on to say
“This does not, by itself, establish that overdiagnosis is currently
occurring at scale. Population prevalence estimates are dated, use different
methods and should not be treated as fixed biological ceilings.”
”To balance this concern, the evidence does not show that people presenting today are less
impaired than those presenting previously.”
“One of the most important changes over recent decades has been the
increased recognition of ADHD and autism among girls and women.
Research suggests that at least part of the historical sex difference reflected
lower rates of recognition rather than true differences in prevalence.”
Basically he has not said it’s happening yet but we are entering a phase “towards” an increased “risk”of misdiagnosis and over diagnosis. That will include the misdiagnosis of autistic people with other conditions such as BPD. It can go both ways. There are several reasons for this not least the shit system we have and long NHS waits. He very much advocates timely diagnosis and a needs led plus diagnosis system.
And re your last comment you have cut and pasted parts of separate paragraphs to push your own narrative. He was discussing two different issues-the recent use of the word “neurodiverse” (which isn’t the same as having an autism or adhd diagnosis) and how having an autism or adhd diagnosis is not the same as having a few traits.
“This is accompanied by a
far richer, more accepting public language for mental health and diversity,
shared online and through social media. This is reflected in the term
neurodiversity, the idea that variation in brain function, cognition and
behaviour is part of natural human diversity rather than pathology or disorder.
The expression* *emerged in the 1990s, and is a social, not a clinical diagnostic
term (Chapter 4). However, the line between the social and the medical is
beginning to blur. Neurodiversity describes the ordinary breadth of human
variation rather than something to be diagnosed”
Your quote “Most people are sometimes inattentive, anxious or socially uncomfortable. Having ADHD- or autism-related traits does not necessarily mean someone has a diagnosable condition" was within a wider passage very much validating diagnoses in autism and ADHD.
“Attention deficit hyperactivity disorder (ADHD) and autism are
neurodevelopmental conditions, strongly genetically influenced and present
from early life, influencing attention, communication, behaviour, learning and
how people experience the world. With the right adjustments many people live
full lives; some face substantial difficulties and lifelong high support needs.
Traits related to these conditions, including inattention, social difficulties and
emotional regulation, occur to varying degrees across the population, but
having some of these traits, or identifying as neurodivergent, is not the same
as having a diagnosable neurodevelopmental condition. Diagnosis depends
not simply on the early developmental presence of traits, but on their severity,
persistence and impact on functioning.”
